This mod automatically opens ALL the doors that I found in SCOs if they exist, so you haven't to press some key to do that.
Also, there's a functionality of restoring Niko's flat and Roman's taxi garage (for now it works only for restoration, but if it's needed, in the future release there'll be a destruction, too ):
Press F11 to restore Roman's taxi garage, if you are NOT near it.
Press F12 to restore Niko's first flat, so you can walk inside it free. I made it working even if you are already inside the flat.

New version for patch 1.0.0.4Hi, guys!
It's been too long since I've last updated my mod. Sorry for that - I hadn't enough time for playing...
Anyway, here goes a new version for patch 1.0.0.4 (the Fifth), and it works fine, I've tested ;)
Enjoy it. Cheers! :)
